A process of the shifting of a signal of interest down to a frequency at which it may be processed more easily to extract information

The electronic mixing of two signals of different frequency to produce a third signal having a frequency equal to the difference in frequency between the original signals.

A process by which two signals are mixed for the purpose of cross-frequency translation. Integral Nonlinearity (INL) This term describes the absolute accuracy of a converter. It is the maximum deviation, at any point in the transfer function, of the converter's output from its ideal value.

To generate new frequencies by mixing two or more signals in a nonlinear device such as a vacuum tube, transistor, or diode mixer.

The mixing together of two frequencies to produce two other frequencies equal to the sum and difference of the first two.

combine (a radio frequency wave) with a locally generated wave of a different frequency so as to produce a new frequency equal to the sum or the difference between the two

of or relating to the the beat produced by heterodyning two oscillations

To combine two different radio frequencies so as to produce the sum and difference of the two frequencies

The frequency that results when two radio frequencies "beat" together (one frequency minus the second frequency = heterodyne).

Pertaining to the process of mixing two radio signals of different frequencies to produce a third signal that is the difference of the two, that is, to produce beating between the two frequencies.
